Ok, went to shoot 2cc's of prop and fina into left delt just now. Everything went smoothly, pin went in, and when i aspirated the usual air bubbles came up. However after i finished shooting, i noticed 2 little bubbles of blood floating around in the syringe with that little bit of juice that you can never get to. I shot it about 5 min ago, dont notice any problems yet, cant taste the steroids or anything. What went wrong?
